Mid-range aurora alert

A solar coronal mass ejection (CME) is en route to Earth today. It was hurled into space by an M7-class explosion near sunspot 536 on January 5th at 0345 UT. Sky watchers should be alert for possible auroras on January 6th or 7th when the CME sweeps past our planet.

Note: this aurora is not on the scale of last Oct/Nov.
Mid latitude oberservers have a 10-15% chance of seeing an aurora.
